3.79

漸四善增五者，漸謂漸死。欲界漸死，將命終時唯滅四根，謂身、命、意、捨。善增五者，善謂善心，於善心死更增五根，謂信等五。前頓、漸死滅三根等，依染污無記心命終者說，若善心死，於前諸位更增信等故，前三根增至八根，前滅八根增至十三，前滅九根加至十四，前滅十根增至十五，漸死四根增至九根，謂三界善心死皆有信等五也。

'Gradually, four; with a virtuous [mind], five are added': 'gradually' refers to gradual death. When one dies gradually in the desire realm, as one approaches the end of life, only four faculties cease: body, life, mind, and equanimity. 'With a virtuous [mind], five are added': 'virtuous' refers to a virtuous state of mind; dying with a virtuous mind, five more faculties are added, namely the five beginning with faith. The aforementioned sudden and gradual deaths where three faculties cease, and so on, are explained in terms of dying with a defiled or indeterminate mind; if dying with a virtuous mind, the five beginning with faith are added to each of the aforementioned states. Therefore, the former three faculties increase to eight; the former eight faculties increase to thirteen; the former nine faculties increase to fourteen; the former ten faculties increase to fifteen; and the four faculties in gradual death increase to nine. That is to say, dying with a virtuous mind in any of the three realms always includes the five beginning with faith.
